Entanglement Transfer in a Composite Electron-Ion-Photon System
Axel Stenquist, Jakob Nicolai Bruhnke, Felipe Zapata +1
We study how entanglement in photoionization is transferred from an electron-ion pair to an electron-photon pair by fluorescence. Time-resolved von Neumann entropies are used to es…
Photoionization time delays probe electron correlations
Mingxuan Li, Huiyong Wang, Rezvan Tahouri +16
The photoelectric effect, explained by Einstein in 1905, is often regarded as a one-electron phenomenon. However, in multi-electron systems, the interaction of the escaping electro…
Mollow-like triplets in ultra-fast resonant absorption
Axel Stenquist, Felipe Zapata, Edvin Olofsson +5
We show that resonant absorption of smooth laser fields can yield Mollow-like triplet patterns. General conditions for such triplets are derived and illustrated with a super-Gaussi…
Giant counter-rotating oscillations on the attosecond timescale
Jakob Nicolai Bruhnke, Edvin Olofsson, Axel Stenquist +1
We predict an unexplored type of ultrastrong coupling between atoms and intense ultraviolet light that leads to giant population oscillations on the attosecond timescale. These cou…
Harnessing Time Symmetry to Fundamentally Alter Entanglement in Photoionization
Axel Stenquist, Jan Marcus Dahlström
The Grobe--Eberly doublet phenomenon occurs in photoelectron distributions when a field dresses the remaining ion. Its manifestation is due to entanglement between a free electron…
Spin-Polarized Photoelectrons in the Vicinity of Spectral Features
Stefanos Carlström, Rezvan Tahouri, Asimina Papoulia +4
It has been shown by Fano (1969) https://doi.org/10.1103/PhysRev.178.131 that photoionization of a cæsium atom by a laser pulse tuned to the vicinity of a Cooper minimum generates…
